No problem. It was an interesting challenge to find out what was going on.
It can take a while to become familiar with how POV-Ray's macros really work and
how they can be best utilized.

Then back to your code:
How about writing out (appending ?) all the "user macro" calls to a file while
"walking" the array, and then include that file for parsing afterwards ?
If you do it that way then the fore_call macro can return a single value
suitable for the ! operator.

BTW: Are you aware that there are some macro parameters that are never used ?
